50 breadth of base. The rear section B is formed g is a bent bar or catch-rod for holding the ladder-section O in its elevated positions. This rod rests in bearings h h, secured at the top of the section A, and bends backward across the upper step a and over the upper bar 0, as clearly shown in Figs. 3 and 8. This catch-rod is adapted to turn in its bearings on the section A, and when turned backward to rest upon the bar 0 it intercepts a rung l of the ladder O, as shown, and so holds said ladder against a downward movement. This rod is provided with a knob or handle t' of any convenient form, by means of which the workman may, while on the step-ladder or otherwise, operate the catch-rod to hold the ladder-section Where desired.

For the purpose of indoor painting or paperl1anging two of these devices are employed, as shown in Fig. 9, for holding a plank or platform it, forming a scaffold, upon which the workman may stand. The plank rests near its ends upon rungs of the ladder-section and may be held at a relatively high or low elevation by raising or lowering the ladder-sections or by placing the plank upon higher or lower rungs of said sections.

WVhat I claim as my invention is- 1. A structure of the kind described having a pivotally-connected step-section and brace-section, in combination with an extension-section between said, step and brace sec- 2. In a combined laddera step-section and a brace-section pivotally connected, a pair of slide-rests independent of thestep and brace sections and slidingly mounted on the extension-section and held centrally between said sections, pivotal connecting-links joined to said sections and the slide-rests, the latter being provided with projections ff to control the actions of said links, said sections being provided at their upper ends respectively with a step and a tie-bar, in combination with an extension section or ladder occupying said slide-rests and held between said step and tie-bar, substantially as described.

In witness whereofl have hereunto set my hand, this 23d day of March, 1898, in the presence of two subscribing witnesses.

LEONARD G. TIEFEL.
